Very cool! After refusing her food thursday and friday morning, she ate last night, then ate this morning (the last of the prepared food with hamburger in it).
And then tonight I tried just her normal kibble without the hamburger, and she ate it! Hooray!
That leaves me with 7 unused burgers. Yum!
I hope she continues eating well, this is far better for her than the hamburger mixed in - also better for her teeth, nice and crunchy!
She has lots of energy and I caught her with her front paws up on the dining room table trying to get to some food I put there. That's quite a stretch for her, and she did it twice, so I guess it didn't hurt at all.
